IMPORTANT:

Requirements: (Should always works - I hope, fingers crossed)
Fallout 2 GOG version

min. Sfall version  4.3.8 (could work with previous one's but I can't give guarantee)

SCP - Standard Crafting Panel is an in-crafting terminal that will allow you to craft or dismantle any major game item like (weapons,armors,drugs,explosive,ammo etc) and some minors as well (Water flask, Stealth Boy, Geiger Counter, Motion Sensor).


WHATS MORE:

There are new 6 crafting items added to the game:
Leather scarps
Metal parts
Electronics
Explosive material
Weapon parts
Medical Supplies 

From which you can craft almost anything (excluding unique quest items and some other things).

SCP also give a bit more meaning to your skills, there are all required to both dismantling and crafting new ones. 

HOW TO GET SCP:

Simple, just finish your temple of trials - it will be added to your inventory.

New game save file is required. :( - unless upgraded from previous version

DISMANTLING MECHANICS

Formula for calculating how much scrap you will get from item is as follow:

For Leather Jacket:

Dismantle skill required (DSR): Outdoorsman 15 
Craft skill required (CSR): Outdoorsman 20

Base required item_1: Leather Scraps 25

Item value: 250 $

For Player Skill (PS):

Outdoorsman:15

Modifier: 50-(DSR-PS)

Player will get:
25 * (Modifier)/100  -----> 25*(50-(15-15))/100 -------> 25*(50)/100 ----> 25*0,5 ---> 12,5 

So with minimum skill player only get half of the value in mats.

Item can have up to 3 skill requirements and only difference is in Modifier where all skill are taken into account.

Maximum yield of 100% mats items starts with 100 point more then required skill level.
In this example player will get 25 Leather Scraps when he/she will have 115 or more Outdoorsman skill points. 

CRAFTING MECHANIC

Very similar but formula is as follow:

Modifier: 50-(CSR-PS)

25 * (100+Modifier)/100  -----> 25*(100+50-(20-20))/100 -------> 25*(100+50)/100 ----> 25*1,5 ---> 37,5 

Maximum cost of mats items with minimum skill required is 150%. In this example player is required to have 38 (maybe 37 I forgot which one :( ) Leather Scraps.
When he/she will have 120 or more Outdoorsman skill points, cost is dynamically reduces to 100%  => 25 Leather Scraps. 

Both Crafting and Dismantling rewards player with small xp bonus (Dismantling gives 1/10 of original item value (Jacket example 25 XP) and Crafting 1/2 (125 XP)

For more details please look into SCP.xmls document - almost everything is written there.  

Hope you all enjoy :)
